Problem: I have a blockage in what appears to be the Main Stack / Vent, blocking only the sink in my second floor bathroom. I was able to get through the sinks brown/metal 1.5 inch pipe with the Flex shaft, only to be completely blocked in the darker Main pipe, which vents to the roof, and runs the full length of my house.
The blockage appears to be just below the point where the sink pipe drains into the main pipe. It takes a few hours for water to drain out of the sink. The other symptom is that when I flush the toilet, the tub gargles, but both the tub and toilet have no issues with backup.
Question:
What's the best / safest way to break through this blockage given the tools I have (Listed below), or purchase? I believe I only have 2 access points, one is the roof, which is pretty severely sloped, and not very safe, however I do have a long enough hose if need be.
In the second to last pic, there also is a clear out point, pretty close to the floor of the basement. Going up would be tough, but with 25 feet on both the flex shaft and auger, I believe I could reach it, fighting gravity of course.
I believe it's a straight shot up that main pipe, hopefully at least, if I have to go up it.
Tools:
I've invested a decent amount in order to try to get this done on my own, so I have:
- 25 inch powered auger from Ryobi,
- Ridgid Flexshaft,
- the Ball Head,
- single chain (1.5-2 inch width)
- double chain with Carbide Tips (1.5-2 inch width)
- Endoscope with Straight and Side angle view
- Medium sized plumber wrench + Tube
- Decent 1/2 Inch Impact Wrench (May need adapter to get basement access open)
Any advice would help!
